Oven display is lit, but buttons/knobs do not start heating, and there is no error code.

Safety: No internal access required for initial checks.

• Check timer mode: Ensure the timer is set to manual mode (often indicated by a hand symbol). Cancel any delayed start or automatic programs.
• Child lock: Some Leisure models have a child lock; refer to the manual to disable it.
• Knob inspection: Confirm that the function and temperature knobs are not cracked or spinning freely on their shafts. Replace knobs if they do not engage the switch.
• Selector switch test: If controls appear to work but no heating occurs, the selector switch may be faulty and require replacement.
